Answer:
- For the statement , the reason is: <em>Subtraction property of Equality</em>
- For the statement , the reason is: <em>Division property of Equality.</em>
- For the statement , the reason is: <em>Substitution property of Equality.</em>
Step-by-step explanation:
The missing pictures are attached.
We must remember that:
- The Subtraction property of Equality states that:
- The Division property of Equality states that:
- The Substitution property of Equality states that:
Knowing this properties we can identify the missing reasons that correctly complete the proof.
- For the statement , the reason is:
Subtraction property of Equality
(Because it is obtained by subtracting 66 from both sides of )
- For the statement , the reason is:
Division property of Equality
(Because it is obtained by dividing both sides of by -3)
- For the statement , the reason is:
Substitution property of Equality
(Because it is obtained by substituting the value of "x" into )
